hi all I appologize if this has been asked before, but I
didnt see it when searching.  I am looking for a way to
have the client computers on the network automatically
download the windows updates from a server on the same
network.  I also want to be able to pick each update that
would be installed.  does anyone know of an inexpensive
way to do this?  

thanks
Rob
